Answer 1

Не знаю, правильно или нет. простите если не правильно. крч сами знайте

Answer 2

Sure, I can help you with that. Let's break it down step by step:

$51.3^2$ means 51.3 squared, which is $51.3 \times 51.3$.

$11.3^3$ means 11.3 cubed, which is $11.3 \times 11.3 \times 11.3$.

$113.9^2$ means 113.9 squared, which is $113.9 \times 113.9$.

$73.9^2$ means 73.9 squared, which is $73.9 \times 73.9$.

Now, let's substitute these values into the expression:

$51.3^2 - 11.3^3 = (51.3 \times 51.3) - (11.3 \times 11.3 \times 11.3)$

$113.9^2 - 73.9^2 = (113.9 \times 113.9) - (73.9 \times 73.9)$

Now, you can calculate each of these separately and then subtract the results. If you have a calculator, it should make things easier. Let me know if you need further assistance!
